Wet adhesion, ICI viscosity, and scrub resistance of a paint are improved by incorporating into the paint a binder that comprises a film former and polymeric composition. The polymeric composition comprises either (a) about 15 to about 35 weight percent of substantially non-self-polymerizable monomer, about 30 to about 70 weight percent of a copolymerizable monomer whose homopolymer is water-soluble, and about 10 to about 35 weight percent of a wet adhesion promoting monomer, or (b) about 35 to about 65 weight percent of the substantially non-self-polymerizable monomer and about 35 to about 65 weight percent of the wet adhesion promoting monomer. The polymeric composition and film former are substantially inseparable by chromatographic means.

Paints and binders for use therein

The ICI viscosity of a paint is improved by incorporating into the paint a binder that comprises a film former and polymeric composition. The polymeric composition comprises about 30 to about 50 weight percent of a substantially non-self-polymerizable monomer and about 50 to about 70 weight percent of a copolymerizable monomer having a water-soluble homopolymer. The polymeric composition and film former are substantially inseparable by chromatographic means.

Paints and polymers for use therein

Permanently flexible and non-tacky coating mastic and caulking compositions having improved heat-age stability contain (a) at least one polymer having a T.sub.g of about -50.degree. C. to about -10.degree. C. and pendant functional groups attached to the polymer backbone and having the formula: ##STR1## in which R.sub.1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano; (b) a zinc-containing pigment (e.g. zinc oxide); and (c) a polyphosphate anion in an amount effective for increasing the wet adhesion of the compositions, particularly of aged compositions. The mastics and caulks typically have total non-volatile matter concentrations of about 60 to about 90 weight percent of which about 15 to about 75 weight percent comprises the described polymer and about 25 to about 85 weight percent is the zinc-containing pigment and other non-volatile solid matter other than the polymer such as fillers, other pigments, etc. The liquid portion of the mastics and caulks may be a polymer solvent, aqueous polymer dispersant, or other material. The cured compositions exhibit exceptionally good wet adhesion to architectural structural materials, especially to materials having relatively non-adherent surfaces such as foamed polyurethane roof insulation and smooth surfaced elastomers and plastics, even after heat aging.

Latex paints

The ICI viscosity of a paint is improved by incorporating into the paint a binder that comprises, in part, a supplemental polymer. The supplemental polymer comprises about 20 to about 60 weight percent of a substantially non-self-polymerizable monomer and about 40 to about 80 weight percent of a copolymerizable monomer having a water-soluble homopolymer. The supplemental polymer and binder are substantially inseparable by chromatographic means.

Mastic and caulking coated substrates

Permanently flexible and non-tacky coating mastic and caulking compositions contain one or more polymers having a T.sub.g of about -50.degree. C. to about -10.degree. C. and pendant functional groups attached to the polymer backbone of the formula: ##STR1## in which R.sub.1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano. The mastics and caulks typically have total non-volatile matter concentrations of about 60 to about 90 weight percent of which about 15 to about 75 weight percent comprises the described polymers and about 25 to about 85 weight percent is non-volatile solid matter other than the polymer such as pigments, fillers, etc. The liquid portion of the mastics and caulks may be a polymer solvent, aqueous polymer dispersant, or other material, and the cured compositions exhibit exceptionally good adhesion to architectural structural materials, especially to materials having relatively non-adherent surfaces such as foamed polyurethane roof insulation and smooth surfaced elastomers and plastics.

Mastic and caulking compositions

Textile materials having improved physical properties comprise woven and/or non-woven fiber assemblies, the fibers of which are bound to a polymer composition containing polymerized carboxylic acid ester monomers and pendant functional groups attached to a polymer backbone and having the formula: ##STR1## in which R.sub.1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano. Such polymers markedly increase wet and dry strengths and shape retention of textile materials, and they improve other physical properties without the necessity of employing formaldehyde-releasing monomers, such as the N-methylolamides, or cross-linking agents. Methods for producing such textile materials by applying solutions or dispersions of the described polymers to fiber assemblies are also provided. Aqueous dispersions of these polymers are particularly useful for the manufacture of loose-weaves, knits and non-wovens.
